Twenty-eight lacto vegetarians also age- and sex-matched controls were questioned about their dietary habits, especially the frequency of consumption of acid fruits, drinks and foods, as well as their dental health habits. Samples of stimulated saliva were collected in connection with the clinical and radiologic study. Plaque, Gingival and Calculus Indices weren’t significantly different in lacto vegetarians and controls. Of the lacto vegetarians 76.9% and of the controls none had dental erosions on some tooth surfaces. In lacto vegetarians the rate of flow of stimulated saliva was lower than in controls but did not decrease with advancing age as it did in controls. Salivary pH was lower in lacto vegetarians than in controls.
